Hey Corrie, I set up a frontier defense leaderboard. You can find it at: https://www.speedrun.com/titanfall/individual_levels

Make sure to view the game and category rules before attempting/submitting a run. Let me know if you have any questions, comments, or concerns.

After replacing these files with my GOG install it says:

No disc inserted. Please insert the original "Crysis(R)" CD/DVD.

Is there a way around this?

I can't be for certain, but I'm pretty sure the only difference is the initial loading time, and this won't effect future runs because time will start after the loading screen or after initializing the tutorial for the 100% category. I believe everything else is the same on all versions of the game, but don't take my word for it.

Post questions, comments, or concerns here. I will try to get back to you as soon as I can.

To anyone who submitted a run before September 7, 2016, you may have your leaderboard time adjusted. The reasoning for this change is to give new runners of the game a chance to set records that might not have otherwise been possible. With the new declared rules for each category runners can properly time themselves and make competition fair for everyone else. Sorry for the inconvenience this may have caused you, but it was necessary to help balance the leaderboard, it’s nothing personal. If you have any questions or concerns feel free to post them to the Q&A thread.
